SPECIFICATION forming part of Letters Patent'Noi 636,015, dated October 31, 1899.

I Application filed February 13, 1899. $erial No. 705,420. (No model.)

To (tZZ whom it may concern.-

Beit known that I, CARLTON F. WARNER, a citizen of the United States, residing at Ticonderoga, in the county of Essex and State of New York, have invented a new and useful lVindow-Screen, of which the following is a specification.

This invention relates to window-screens; and the object of the invention is to provide a simple and eflicient device of this character and means for supporting thesamewherein the parts are constructed wholly of metal, thereby particularly adapting the same for application to fireproof buildings.

The screen involves in its construction a metallic frame, preferably of sheet metal, and a netting which is held in place by flanging or crimping portions of the frame over the netting to hold the latter firmlyin place without employing tacks or other fastening devices, and in connection with the 'screen- I employ guiding means for the same, consisting, preferably, of two strips secured to the window-frame outside of the window, by reason of which said window is easily accessible from the inside of an apartment, and which guiding means includes two substantially U- shaped metal strips from which ears are punched, theintegral structure thus obtained being capable of manufacture at a low cost. The cars specified constitute means through which rivets or other analogous devices can be passed to hold the two guide-strips in place, and the stiles of the screen-frame are disposed within said strips,whereby the screen can be properly guided, and the inner faces of said strips are adapted to frictionally engage the screen-frame in such a manner that the latter can be readily raised or-lowered, but can also be held in an intermediate position.

With these ends in view the invention consists in the novel combination of elements and in the construction and arrangement of parts, which will be hereinafter fully described and claimed.

To enable others to fully understand the invention, the preferred'embodiment thereof is illustrated in the accompanying drawings, forming a part of this specification, and in which- Figure l is a perspective view of a window frame provided with a screen and guiding means therefor constructed in accordance with the invention. Fig. 2 is a longitudinal central section of the screen. Fig. 3 is a crosssection taken on the line 3 3, Fig. 2. Fig. 4 is a perspective detail of a. corner of the screen. Fig. 5 is a detail of one of the guidestrips.

Like characters denote like and corresponding parts in each of the several figures of the drawings.

The window-frame is designated by A, and the upper and lower sashes by 2 and 3, respectively, said sashes being mounted in position in the usual manner.

The screen-frame, which is located outside of the plane of the uppersash 2, is designated by B, and it is preferably made of sheet metal and consists of the side bars or stiles 4 and 5 and the top and lower bars 6 and '7, respectively, the bars or cross-pieces 6 and 7 being fitted within spaces formed between the main portion of the side bars and the flanges L and 5 thereon, said flanges being turned or lapped over the cross-pieces 6 and'7 to hold the latter firmly in place, as shown at 4. By the provision of the flanges 4E and 5 it will be evident that they serve not only to hold the cross-pieces 6 and 7 in place, but to present an even and rounded outer edge, thereby preventing said edge from cutting the fingers or marrin'g or defacing the windowframe. The cross-pieces 6 and 7 are also provided with inturned flanges 6 and 7, which present a rounded edge upon the upper and lower sides of the frame for the purpose pointed out, and said flanges are bent upon themselves underneath the upper and lower extremities of the side flanges 4 and 5. The structure thus formed is then rolled along theflanges, whereby a solid metallic frame is produced and being wholly of sheet metal can be manufactured at a low cost from galvanized iron or other sheet metal primarily intended for application to metal windowframes used principally in fireproof buildings.

While the frame and its combined guide and holder, hereinafter more particularly described, are preferably made of galvanized iron, it is obvious that they may be otherwise formed, although the metal specified cannot rust or be affected by dampness, &,c.

The netting is designated by 8, and it consists of a suitably-shaped piece of metal of reticulated material, which overlaps and lies against the four parts of the frameB, said netting being held in place by the inturned flanges 9, struck from the side bars l and 5 and cross-pieces 6 and 7-, respectively, of the frame, these being crimped inward to engage the inturned portions 10 of the netting, and when it is assembled the flanges are rolled or otherwise pressed firmly against said netting to hold the latter tightly in place without the employment of other fastening means.

As heretofore set forth, the screen-frame B is preferahlylocated outside of and below the fixed upper sash 2, and for guiding the same in its vertical movement and holding it in a fixed position I prefer to employ the metallic strips 12 and 13, respectively, which are substantially of U shape and within which the side stiles 4 and 5 of the screen-frame B are disposed, said guide-strips being adapted to frictionally engage the frame in sucha manner as to permit the same being readily raised or lowered and sufficiently to hold the same in an intermediate position.

As a convenient means for holding the guide-strips in place each is provided with a series of cars or projections, as 1+1, 15, and 16, stamped or cut from the outer portions of each of the same and bent at right angles thereto, said ears being adapted to engage flatwise the outer blind-stops and to be held in place by fastening devices, as 17, passing through the same and into the window-frame. The height of the guide-strips 12 and 13 equals, substantially, that of the screen-frame, and by reason of the frictional engagement between said parts the screen-frame is held firmly at all points in its height and against rattling,which is particularly advantageous during windy weather. The lower cross-piece 7 is provided with a finger-piece, as 18, by which the screenframe 13 can be raised or lowered.

lly cutting away the metal'from one of the flanges to form the angular attaehingears 14 and 16 the length of said flange is reduced as compared with the uncut flange, and this facilitates the introduction of the screen-frame to the guides, it being only necessary to pass the lower edge of the screen-frame over the top of the short flange until it strikes against the longer flange, whereupon by moving the screen-frame downward its side bars are engaged between the two flanges of each guidestrip.

It will be understood that the frame c011- structed as aforesaid can be used equally as well With doors or other openings. \Vhen used as a door-screen, the frame of course will be hinged to the door-frame.

Changes in the'form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, what I claim is 1. A screen frame composed entirely of metal and comprising side, top, and bottom bars, each consisting of a sheet-metal strip having its longitudinal edges bent over to form outerand inner flanges, which lie against or in parallel relation to the body of the strip, 011 the same side thereof, the extremities of the top and bottom strips being clamped beneath the outer flanges of the side strips, and

the screen fabric bent at its edges to extend around the outer edges of the inner flanges of all the strips, said inner flanges being pressed inward by rolling so as to bind the fabric against the body of the several strips, substantially as described.

2. As an article of manufacture, a guide for the purpose specified, consisting of a sheetmetal strip bent into U shape in cross-section to form substantially parallel flanges, one of said flanges being transversely incised near each end and the metal defined by such incisions bent outward at right angles to the other flange in such manner as to lie flatwise against the surface to which the guide is secured, thereby making one flange shorter than the other for facilitating the entrance of the device to be guided therein, said bent portions forming attaching-cars which are perforated for thepurpose specified.

In testimony that I claim the foregoing as my own I have hereto, affixed my signature in the presence of two witnesses.

CARLTON F. \VARNER.
